Application filed April 18, 1907. Serial No. 369,380.

To all whom it may concern:

Be it known that I, MADs H. MADsEN, a citizen of the United States ofAmerica, and resident of Kimballton, Audubon county, Iowa, have inventeda new and useful Hay- Handling Mechanism, of which the following is aspecification.

The object of this invention is to provide improved means for receiving,supporting and laterally dumping hay in a barn or mow.

A further object of this invention is to provide improved means forsupporting hayhandling mechanism in a barn or mow.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, ointed out in my claims andillustrated y the accompanying drawing, in which Figure 1 is a plan ofone form of'my im roved device in position for practical use. ig. 2 is aside elevation of the same device in position to receive a qiliantity ofhay. Fi 3 is a cross-section of t e deviceon the in icated line33 ofFig. 1. Fig. 4 is a cross-section on the indicated line 4-4 of Fig. 1.Fig. 5 is a plan of a modified form of my device. Fig. 6 is a sideelevation of the form shown in Fig. 5. Fig. 7 is an enlarged detailview, in side elevation, illustrating the means em loyed to clamp asupporting device to a ca le.

In the construction and mounting of the device as shown, the numeral 10designates a hanger bar provided with track rollers 11 ada ted to travelon a track 12 and support.

sai 'bar. The hanger bar 10 and rollers 11 may be adapted in form to anydesired track,

but in this mstance I show the bar forked in its u per end to straddlethe track and provide with a roller on each arm and extending inwardlytherefrom to contact with the upper surface of the track 12, said tracksupported in any desired manner from rafters 13 of a barn or mow. Aroller or pulley 14 is mounted on the fork of the hanger bar 10 belowthe track 12 and is adapted to support the draft ro e of the hay-fork orslings (not shown) emp oyed to lift and convey hay to the mechanismillustrated. A supporting bar 15 is pivoted at one end to and extendsforward from the lower end of the hanger bar 10. A cable 16 is fixed atone end to the supporting bar 15 in front of the hanger bar and extendsthrough a pulley 17 in the fork of said hanger bar above'the su portingbar.

he pulley 17 within reach of the operator. Straps 18 are.

provided and each stra maybe formed in two pieces hinged toget er andhaving eyes 19, 20 on their extremities. The straps 18 may be mounted onand embrace the for ward end of the supporting bar 15 or they.

may be located midway of the length of the bar as shown by dotted linesin Fig. 2.

Arms 2 1 22 are mounted by the insertion of their rear end portions inthe eyes 19, 20 of the straps 1S and are secured therein preferably bybolts or pins 23 extending through said eyes and arms and serving theadditional purpose of clamping the straps to the supporting bar. Thearms 21, 22 extend forward and downward in diverging planes from thesupporting bar 15 and terminate in straight portlons 21 22 adapted torest on a cross-tie or collarbeam 24 and hooks 25, 25 adapted to engagesaid cross-tie and prevent rearward movement of the mechanism. It is thefunction of the arms 21, 22 to support the bar 15 and devices and loadthereon supplemental tothe support furnished by the hanger bar 10, andin so doing relieve said hanger bar of a material portion of strain towhich it other-t wise would be subjected. The arms 21, 22 are adjustablewithin limits longitudinally of the bar 15, through changing positionsof the straps 18 as indicated, for the purpose of adjusting the extremelength of the apparatus in respect of the distances of separation ofcross-ties or collar-beams 24, which may vary considerably in differentbarns. A bearing 26 is mounted loosely for rotary oscillation on theforward portion of the supporting bar 15 and a shaft 27 is mounted inand extends transversely of the lower portion thereof below said bar.Brackets 28, one only of which is shown in Fig. 2, are mounted forrotary oscillation on or with the shaft 27 and a U- V shaped frame 29 ismounted on said brackets. The frame 29 is arranged with its closed endportion rearward and the brackets 28 are arranged beneath the centralportions of, the sides or arms of said frame.

Crossing braces 30 may be mounted on and connect the sides of the frame29. The bearing 26 is forked and a collar 31 is mounted on thesupporting bar 15 within the fork thereof and is secured to said bar, asby a transverse pin 32. i A stem 33 is formed on and rises fromthecollar 31 and springs 34, 35 connect the upper end of said stem tothe sides of the frame 29. It is the function of the springs 34, 35 tocenter the frame 29 V above the supporting bar 15 and return said frameto normal position as shown. A rope 36 has its center beneath thesupporting bar 15 and extends upward on opposite sides of said barthrough pulleys 37, one only of which is shown in F ig. 2, on the sidesof the frame 29 and near the closed end portion thereof, and extendsthence to points of attachment at its ends on the ends of a crosshead 38fixed to and extending transversely of the supporting bar adjacent thehanger bar 10. A cable 39 is fixed to and depends from the center of therope 36 beneath the supporting bar 15, within reach of the operator. Ayoke 40 is fixed to or formed on and extends downward and forward fromthe cross-head 38.

vated and conveyed, by a In the practical use of this device themechanism is adjusted as to length and then is moved longitudinallyof'the barn into the desired position by manipulation of the cable 16,said cable serving to lift the supporting bar and arms and frame thereonso that the hooks 25' clear the cross-tie or collar-beam 24 and permitsuch longitudinal movement of the mechanism. When the mechanism islocated to the satisfaction of 'the operator, the'frame'29 occupies aninquantity of hay on the frame 29, and said frame is'tilted laterally bymanipulation of' the cable 39 and rope 36 in contact with and straininglaterally against the yoke 40, thus depositing'the hay from the frame'toone side or the other of the median line of the barn. The direction oflateral tilting of the 'fram'e'29 is determined by engaging the cable'39 or rope 36 with one side or the other of the yoke-40.

After the portion of hay is dumped laterally from the frame 29, thedraft on the cable 39 is relaxed and one or the other of the springs 34,35 returns the frame 29 to normal position in respect of lateral'tiltingand the said frame over-balances forwardly into the inclined positionshown in Fig.

2 preparatory to receiving another load.

'When the desired number of loads or portions of hay have been dumpedlaterally from the frame in one location, the entire mechanism isshifted to another location by manipulation of the cable 16 and isre-set with the arms 21 22 supported on another cross-tie orcollar-beam.

In the construction of the mechanism as shown in Figs. 5, 6 and 7 thefollowing changes are made: Arms 21, 22 are connected to the supportingbar 15 by one or more clamping straps 18 in like manner and in the sameplace as the arms 21, 22 are connected as above described, and theextreme length of the apparatus may be adjusted as indicated. The arms21, 22 extend forward and upward in diverging planes from the strap 18and terminate in hooks 25, 25, and a pulley 21 is mounted, in each hook.Cables 24, 24, are mounted longitudinally of the barn or mow on oppositesides of and in a lower plane than the track 12 and the )ulleys 21 inthe hooks 25 ride on said cables and support the arms 21, 22, which armsin turn support the forward portion of the bar 15. Forked levers 41, 42are mounted for oscillation on the hooks 25, a pair of levers to eachhook, and a spring 43 connects said levers above the fulcrums thereofand causes the forks of the levers to engage the cable 24, or 24", onopposite sides of the pulley 21 and clamp said cable to said pulley.Links 44, 45 are connected to the lower ends of the levers 41, 42 andare connected at their opposite ends to a ring 46, and a rope 47 dependsfrom each ring and connect below the lowermost portion of the frame 29with a draft rope 16. The rope 16 is omitted. The frame 29 and means ofmounting on the bar 15 follows the form shown in my companionapplication pending concurrently herewith, but it can be made as'shownin Figs. 1, 2 and 3, and it is operated in the manner shown anddescribed in connection with the latter figures. The mechanism is movedinto any position longitudinally of the track 12 by applying draft orrope 16 sufficient to release the clamping contact of the levers 41, 42on the cables 24", 24 and then pulling the mechanism endwise by the samerope. Whenever draft is released from the rope 16 the springs 43 applythe clamping function of the lovers 41, 42 to the cables 24, 24 and holdthe mechanism stationary.
